所谓台极投影图就是以本台为极点,以对蹠点为另一极点的,按照方位角、地心距的一定间隔做成的球面投影图。要以世界地图为底图,就是说做世界的台极投影图,则方位角α与地心距△均以10°间隔为宜。列成下表:
The so-called Taiji projection map is the extreme of this station to the other plantar point for the other pole, in accordance with the azimuth, the distance between the center of the earth made of a spherical projection. To the world map as the base map, that is to say the world’s Taiwan polar projection, the azimuth α and the center of the distance △ are 10 ° intervals appropriate. Listed in the following table:
